APPARATUS FOR TRANSFERRING BOTTLES 0R CONTAINERS FROM ONE LEVEL TO ANOTHER ll Filed Oct. 20, 1930 3 Sheets-Sheet 3 I NVENTOR ArithuvGuqnoek ATTORNEY Patented Sept. 1, 1931 UNETED STATES PATENT- OFFICE ARTHUR GUY ENOCK, F WEMBLEY PARK, ENGLAND APPARATUS FOR TRANSFERRING BOTTLES OR CONTAINERS FROM ONE LEVEL ANOTHER Application filed October 20, 1930, Serial No. 490,058, and in Great Britain October 5, 1929.

This invention relates to transferring bottles or containers from one conveyor to another at different levels more particularly in apparatus such as described in the specifications of my previous U. S. Patents Nos.

1,649,393 and 1,741,925 for pasteurizing milk in bottles in which the bottles are traversed through chambers of different temperatures placed in tiers one above the other. The inlo vention may however be applied to other purposes for example for conveying trays or containers of material from one level to another.

The apparatus comprises a number of vertically moving rods or pedestals mounted in rotary frames to revolve round a central axis, each fitted with a table or platform to receive a bottle or container and raised and lowered by a ramp or cam surface.

The invention will be fully described with reference to the accompanying drawings Fig. 1 is a diagrammatic elevation sh0win one form of the transfer apparatus.

Fig. 2 is a sectional plan on line 2-2 Fig. 1.

Fig. 3 is an elevation of the lifting pedestals and tables.

Fig. 4 is a plan part in section of the pedestals and tables.

Figs. 5 and 6 are an elevation and plan respectively of another form of the invention.

The apparatus is constructed with a number of vertically moving rods or pedestals A mounted in. a rotary frame B to revolve around a centre in either a circular, elliptical or other path and an inclined ramp or cam surface D from which the rods or pedestals A are suspended and by which they are raised and lowered as they are carried round with the rotary frame B. Each pedestal or rod A is fitted with a platform or table E to receive a bottle or container in which is maintained horizontal during the vertical movements of the pedestals to enable bottles or vessels filled with milk or other liquid to be carried thereon without spilling. The rotary frame B comprises upper and lower annular members 5 and 0 vertical guide bars 6 between said members.

The annular members I) are fixed against vertical movement and form guides through which the pedestals or rods A'slide. The ramp or cam surface D may give a continuous up and down movement to the pedestals or rods or it may be of a shape to give a rest or dwell at the top or bottom of the lift or both. A star wheel F, mounted on a rotary shaft or spindle, maybe disposed adj acent to the revolving pedestals A at either the top or bottom level to transfer the bottles w on to the tables or platforms E.

In Figs. 1 to 4 the lifting and lowering apparatus is shown in conjunction with traversing conveyors 1 by which the bottles may be moved in zig zag fashion through one of the pasteurizing chambers described in the U. S. specifications Nos. 1,649,393 and 1,7 41,925, the bottles being delivered by the. conveyors 1 to a conveyor 2 fromv which they are taken by the star wheel F and successively delivered to tables or platforms E carried by the pedestals A and are lowered by said pedestals to the level of another chamber. Corner guides 4 above the conveyors 1 direct the bottles from one conveyor 1 on to the next as they are moved through the chamber. The rods or pedestals A are suspended by chains or cables at from sprockets or pulleys (Z, one end of each chain or cable being attached to the pedestal and the other end to the member I) of the frame B. The sprockets or pulleys d are i mounted on spindles d journalled in verti-' cally sliding blocks 612 adapted to slide vertically on the guide bars 12 A roller 03 mounted on each spindle (Z rolls round the inclined ramp or cam surface D. The frame B is secured to a central shaft which is revolved by the gears b and the rollers (Z as they run round the ramp D, each simultaneously raises and lowers one of the sliding blocks (Z and the sprockets dearried by such blocks. Since each chain or cable a has one of its ends connected to one 7 of the pedestals A and its other endconnected to the member I) of the frame B, the pedestals are caused to move downwards or upwards twice the vertical distance traversed by the sprockets d. As the pedestals A revolve round the centre column B the bottles a: are transferred in succession from the conveyor 2 by the star wheel F on to the tables or platforms E and are lowered to i the level of the conveyor 3 and are removed from the tablesor platform-E by the guides B 4. The. rods or pedestals A are suspended by'chains or. cables a" which passround 29, sprockets or pulleystl carried'by the frame B,- one adjacent each of the pedestals A,

and also around sprockets or. pulleys (l which ELIG-kGYECl tO the upper ends of spindles journalled inblockscl slidable on guidebarsor-slidewaysjb Wl1-1Cl1 extend'lnwar-dly from'the'frame B toward-the center of the latter. Each'of the chains orcables a has itsv opposite end'connectedzto-the frame B.

Rollersrll, securedito the'lower: ends of a said-spindles, bear against-a-horizontal cam trackD secured to the central column B within the frame .13, so that,.asthe frame B rotatessaroundthe cam track D the slidingz blocks (Z? and sprockets (F? are caused as by engagement of the rollersal with the cam. track. D tomove toward and away from, the centreof the frame B: Theto and fro a movement of the sliding blocks J and sprockets -orpulleys: cl raise and lower thechains or. cables-aa-nd; with them. the

Vertically sliding;v pedestals or. rods A and thetablesorr platforms E. thereon. Thus the engagement of the-.rollers-d with the camrtrack-iD notion-1y causes movement of the' sprockets? or pulleys (Z- radially of the frame .13 bu-talso imparts rotation to said sprockets orpulleys. The bottles are trans ferred. to and: from the tables or platforms E; as. before described from conveyors at 5Q; therespective levels.

What I claim= as my. invention and desireato protect by Letters l Patent is 1.. Apparatus for transferring containers from one level; to another, comprising a.

ii; framemember and a cam member, .saidrmembersbeingn'elatively rotatable, a plurality of container-supportingpedestals *VQl'tlOZlllY movable relatively to'said -frame,.a plurality of. shaft supporting members each having; a new shaft gourn-alled (therein, a rollerand 1 a pulley keyed to.-eachof= said shafts-, said; rollers engagingsaid cam'member, and aplurality of, flexible: members movable, respectively, over saidlpulleys, each :of said rflex-iblevmem- 6. berschaviugnnebf itsiendszsecured to said frame member and its other end secured to one of said pedestals.

2. Apparatus for transferring containers from one level to another, comprising a rotary frame, a plurality of container-supporting pedestals vertically movable relatively to said frame, a fixed cam track, a plurality of rollers movable on said cam track, pulleys carried, respectivel by said rollers, and flexible members each movable over one of said pulleys and having its opposite ends connected, respectively, to one of said pedestals and to said rotary frame.
